This is not a foolish question, it is a brilliant question, but at the same time we must know that there is no human formula to enter the kingdom of heaven, but all this is about grace, an undeserved gift that God gives us through the death of His Son on the cross of Calvary.
But if we talk about entering the kingdom of heaven there is something that is proper to each believer: “Born again”. We can not say that we are Christians if we are not born again, this is the distinguishing mark of each one of us and our beloved Lord Jesus Christ spoke about the new birth:
3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother’s womb, and be born?
5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Nicodemus was a teacher of the law, a man who represented the knowledge of Israel, however, he knew nothing about the new birth. Let’s not fall into the deception of being inside the temple and being part of it and not being a born again creature and that has knowledge of it.
It is true that there are no human formulas to enter the kingdom of heaven, the truth is that if we are really Christians this means that we are born again people who have renounced sin, the world and its desires.
God has given us the new birth through the death of His Son on the cross and thanks to it we are saved and being saved makes us have good works, worthy to show that we are new creatures.
How to enter the kingdom of God
Who is interested in the Kingdom of God? Those who have believed in Jesus Christ and want to be with Him, in his presence; those that don’t love the works of people of this World, nor are they participants in what the ungodly do.
That kingdom is not of this World: Jesus said it is not constituted here on this earth, but it is one which is in Heaven.
“Jesus answered, My kingdom is not of this world:” (John 18:36).
How to enter the kingdom of God?
On one occasion the Lord spoke to Nicodemus, a chief among the pharisees who wanted to meet Jesus; and…
“Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.” (John 3:3)
There is a condition we must fulfil to enter the Kingdom of heaven: to be born again. This is impossible for a person; and Jesus added that we need to be born from the spirit, that is to say, to be new creatures by faith in Him, and to be cleansed by water to purify our spirit. It means to believe and be baptized in the name of Jesus Christ.
Besides, the Lord Jesus Christ speaks to people about changing our behaviour and about having a new spiritual character. We must be as little children (Matthew 18:3)
Those who want to enter the Kingdom of Heaven need the work of the Holy Spirit in their souls, in order to become new creatures in Christ. This is needed so that their way of living is changed; and to the end that, in singleness of heart, they can effectually give up their malice and evil conversation, and live in love to God, to brothers and to people in general.
Truly this must be the work of the Spirit of God in our lives: it is He who leads us through a progressive change of life for the glory of God. We live not by good works but by the grace of God.
“Listen, my beloved brothers, Has not God chosen the poor of this world rich in faith, and heirs of the kingdom which he has promised to them that love him?” (James 2:5)
We are poor in spirit, like little children, and many times poor in goods of this world. But we are rich in faith, and God has chosen us to be heirs to his kingdom, which he has promised to those that love him through Jesus Christ. Amen. Let’s give glory to Him forever.
